Doctors are dunking on the Midjourney Medical full‑body scanner
Here’s why:
1/ False positives, overdiagnosis, and overtreatment
It's not hard to generate “abnormal” findings (benign lesions and tumors)
This leads to: follow-up imaging → specialist visits → biopsies → potentially surgery
At population-scale, overdiagnosis + overtreatment can lead to more deaths and complications than lives saved, counterintuitively
2/ False negatives
Full body scans also miss things (e.g., early colon or lung cancer) and are not a substitute for colonoscopy, mammography, or low‑dose CT in defined high‑risk groups
3/ The Function Health parallel
Most doctors cannot read a 100+ biomarker Function blood test or 20+ pages of MRI data from Ezra/Prenuvo
It is far outside the scope of what doctors are trained on in med school
That's because these are not the "Standard of Care" (SOC)
Many doctors hate Function/Ezra/Prenuvo because anxious patients come in asking them a bunch of questions they don't know how to answer
(This is happening with peptides now.)
4/ Midjourney's ultrasound is even further away from the SOC compared to Ezra/Prenunvo MRIs
It’s a brand‑new whole‑body ultrasound modality positioned for “body composition maps,” not an FDA‑cleared diagnostic device
It is allegedly ~10x cheaper, ~60x faster, but there's no large‑scale clinical validation that it can match MRI on detecting specific diseases across organs
5/ Why this still sells
There is 100% a market here:
Consumers get a tangible artifact (“I’m taking control of my health and getting all this cool data”), and emotionally powerful hero save stories when it works
Cancer is a loaded word. One dramatic “this scan saved my life” anecdote drives way more demand than all the reasons experts push back on, that I mentioned
We'll see how this all shakes out, but overall it's just another example of culture and technology moving far faster than traditional medicine and healthcare
Which is the thing I care about

I've done Prenuvo and helped launch the Ezra x Blueprint scans
Cancer is largely curable these days through early-stage detection. It's really only fatal when detected in later-stage
That's why comprehensive annual scans will become as common as wearables and blood testing, if the price comes down
Kudos - turning an anime image gen cash cow into preventative medicine machines is a breath of fresh air from all the slop startups today
But real ones know that a good sauna in SF is actually the biggest announcement here
